In this study, experiments were conducted to investigate the production of biogas through anaerobic digestion from the co-digestion of palm oil mill effluent (POME) with cow manure. Besides, the effect of co-digestion towards the change of methane composition in biogas was also evaluated. The batch type of digester was used for the digestion and was operated at room temperature, 28 ± 2°C for 10 days. The digester was operated at different VCM / VPOME (volume of cow manure/ volume of POME) ratio of 0.05, 0.10, 0.15, 0.22, 0.29 and 0.36. From the results, biogas production was enhanced by the addition of cow manure to POME. The volume of biogas production was increase from 36% up to 126% with addition of cow manure. In addition, through co-digestion, the percentage composition of methane in biogas was also increases with the increment from 28% to 42 %. This study can provided useful information for the researchers and agricultural practitioners that interested on improving and applying for this type of anaerobic digestion in the future.
